My brother has 4 plants in 3 gallon pots all are in promix hp amended with gaia green power bloom. He waters when the plants are dry . There's lots of wind and sun. He doesn't ph but hasn't the entire time and our city water is right around 7. Two of the plants look ok and 2 look terrible. Any ideas?

Can you get a close-up on the 4th picture I can't tell if it's calcium or potassium deficiency but it's likely caused by the high pH locking something out? Are these all the same strain?

My guess would be the other two are more susceptible to the high ph and are showing the issue, promix likes 6.2

Can you get a close-up of those brown spots on the leaves

Best pics I can get right now. I'll adjust the ph and see what happens the next week or so. Thanks for the help

Couldn't tell from pic if it was a calcium issue or possibly something fungi, looks more like a calcium issue from what I can see, it may well straighten out when you correct the pH
